Who are you referring to as 'he'? There was someone claiming to have an 8hp75 in their car with no adapter, swearing up and down, but never backed it up, is that who you're referring to?

Ah, I didn't know the 6r80 solenoids were controlled externally, that would make it a lot easier. To get trans brake working without an external TCU, probably need to get some wires direct to the solenoids.

My apologies for not being more specific I dont know his name right now, but yes it was the person claiming to have an 8HP75 that bolted straight up no adatper... not an 8HP70 my mistake.

Yes for the trans brake, one way or another youre going to have to wire into the solenoids which would be easier if the TCU was external but I still think its doable in way or another either with bulkhead seal for wires through pan or preferably with unused pin/connector locations on the factory TCU/mechatronic connector.

If there are unused pins, that would make it trivial. Going through the filter would work, but that's a bit sketchy. I wonder how many people would even want trans brake, that's fairly hard core drag racing for setups where brake boosting won't work. It's a bit of a parts killer, too. That said, I'm sure some will definitely want.

At some point I'm going to see if I can find any front diffs that bolt up to the N54 that are a bit beefier, it's been on my list for a while but I just haven't had time.

I agree its pretty extreme, but as you said there will be some who definitely want it. Most of my testers committing right now are pretty damn serious... some extremely so and for them its right down their alley. I do believe it has likely potential to be harder on the trans, just because of the shock force on launch hitting the shafts etc.

If you figure out something with the front diff please let me know, I will start on that later this year/early 2022. I would be happy to share what I find out as well.

So i got my kit from Joshua. It is done and installed and ready to go. Great great fitment of everything. I have a 135i and there is less room in the trans tunnel. Josh took care it it immediately and sent me some different -an fitting for the tight area. Id be driving right now but i broke a rusty ass bolt that holds the shifter cable in place. Waiting on fcp euro now.
Id say to anyone on the fence. Do it. Cant go wrong with the professionalism and attention to detail that was put into these kits. Every bolt screwed in easily and perfect. And dealing with Joshua and Rod Sutphin about the tune has been a pleasure!!!

There used to be a time someone would ask if this transmission could be used seemingly every week. The answer was always a resounding: No you idiot, the software is the limiting factor.

I'm glad to hear that we've finally made it past this. I hope to see some more feedback, videos and some long term results!

Steve you're the first tester to install the kit out of 8 that have currently shipped out. I have 15 total RWD kits that have been sold. 7 are waiting for final payment and shipping but all of them are 100% finished and ready to go. I also have 9 more adapter plates that I am allocating towards AWD setups coming soon. I am very eager to see everyone send it on these transmissions and provide real world feedback!

I havent been posting many updates on social media or in this thread as its been all hands on deck getting these kits finished and out the door. Over the coming months my goal is to finish AWD test kits, ship those and then start another batch for official product launch/release in August/Sept. Research and development for several other transmission adapter kits and misc parts are also on the chopping block for the remainder of this year and into next year.

Thank you to everyone who has supported this project, we are just getting started!
